Dangerously hot temperatures will grip the southwestern U.S. and California this weekend into next week, potentially taking out the previous record-high in Phoenix, where temperatures could top 115 degrees.

“There is absolutely no doubt we will be near all-time highs with this heat wave, with the hottest and most dangerous temperatures expected Monday through Wednesday,” the National Weather Service in Phoenix said, offering heat safety tips.

Forecasted high temperatures Sunday through Tuesday from the National Weather Service.

Daily record highs will be within reach: 115 degrees for Sunday, 118 degrees for Monday and 116 degrees for Tuesday. In fact, Phoenix could approach its all-time record high of 122 degrees set on June 26, 1990.

Phoenix will also be within reach of tying the record for consecutive days of high temperatures greater than 115 degrees, which is four days set in 1990.

The hot conditions are labeled as a classic pre-monsoon heat event for the Southwest region, NWS said. Some of the highest temperatures of the year can be recorded before the onset of the summer monsoon. Humidity levels are low, so the sun’s energy can be used to heat the air rather than being absorbed by water vapor or used for evaporation.

In California, triple-digit heat will engulf Bakersfield, Fresno and Sacramento starting this weekend and continuing into next week. Some daily record highs will be within striking distance, the NWS said. In Southern California, the hottest temperatures will be in the deserts with highs over 110 degrees. Death Valley will see its first mid-120s of the year by early next week.

In Las Vegas, temperatures are forecast to be 110 degrees or hotter this weekend through next week. Lows will only fall into the mid-80s by early morning.
